Page 1 RECUMBENT SAFETY AND RIDING TIPS General Rules for Safe Recumbent Riding 1. Always wear a CPSC approved helmet and some form of eye protection. 2. Always ride with a rear view mirror attached to your helmet or mounted on the recumbent. 3. Obey all traffic rules and regulations, signs and signals. 4. Ride on the side of the road, going in the same direction as the traffic and in single file. 5. Use proper hand signals when turning or stopping. 6. Be alert at all times, especially watch for cars pulling out into traffic or for opening doors. 7. Inspect your Sun Recumbent before every ride. Make sure all nuts and bolts are securely tightened. Check your brakes by applying them and rock your Sun Recumbent forward and back to make sure they are engaging properly. Check your tires for proper air pressure as indicated on the sidewall of the tires. Make sure the quick release levers on wheels and seat are secure. Also check for any other possible mechanical problems. 9. Do not "stunt ride" or hitch a ride on other vehicles. 10. Do not ride carelessly. 11. Use extreme caution when riding in wet, icy or otherwise hazardous conditions. WARNING: J&B Importers, Inc. is not responsible for accidents resulting from failure to comply with all bicycling safety laws. Contact your local authorities for more specific information about such laws. Night Riding Tips 1. Your Sun Recumbent is equipped with front, rear, wheel and pedal reflectors. They should be kept clean at all times, and never be removed from your recumbent. 2. Always use an appropriate lighting system when riding at night. 3. Ride with extreme caution. Be alert for cars, pedestrians, runners and other bicyclists. Ride defensively and watch for road hazards. 4. Wear light colored clothing and use reflective tape on clothing or helmets to help make you more visible at night. WARNING: Reflectors alone are not adequate for night visibility. Use a high quality front and rear lighting system for greater visibility. Page 2 Wet Weather Caution When rims and brakes are wet due to muddy, wet or icy road conditions the distance needed to stop safely increases. You must, therefore, anticipate the additional distance needed to stop in such circumstances. Reduce your speed and take corners slowly and carefully. Hard appli- cation of the brakes on wet or icy pavement (or on loose gravel or debris) can cause the wheel(s) to lock up and skid, resulting in possible loss of control. Slowly apply brakes in a gradual, controlled manner to avoid skidding or loss of control. Recumbent Riding Tips There are some unique features to be aware of that will help you enjoy riding your Sun Recumbent. You may find it helpful to practice riding in an open area, such as a paved, empty parking lot or a traffic-free road. Before riding your Sun Recumbent, please carefully read this manual. This will enable you to familiarize yourself with the mechanical operations. 1. Relax the upper body. 2. Do not pull on the handlebars or tense the shoulders as this leads to over-steering the recumbent. 3. Ride with relaxed pressure on the handlebars. 4. When starting to ride, be sure the recumbent is in a low gear. 5. Get comfortable in the seat, and place both feet on the ground (see Seat Installation, Removal and Adjustment on page-10). 6. While sitting comfortably on your Sun Recumbent, with both feet on the ground, try propelling the recumbent slowly with your feet on the ground. Like walking; left, right, left, right... while gently steering a little to the left and right. Keep walking the recumbent with your feet until you can pick both feet up off the ground an inch and be able to balance yourself and steer comfortably. When you feel comfort able, then you can try pedalling. 7. Stabilize the recumbent by applying the brake, put one of your feet on the pedal and back pedal until the crank is at the top in a vertical position. 8. With firm pressure, push on the pedal; lift the other foot off the ground, as you release the brake and place the other foot on the other pedal. 9. Lean back into the seatback and pedal confidently in an appropriate gear. Propel yourself at a safe and reasonable speed. 10. When riding on level ground or going downhill, lean back and relax. Up hill it sometimes helps to lean forward a little. 11. Before coming to a stop, gear down (while spinning the pedals in a forward motion); this will enable you to start again in a low gear. Page 3 Recumbent Riding Tips (continued) Your body may require some adjustment to the riding position and muscle groups used that the Sun Recumbent promotes. This is natural; adaptation to the new position will vary, depending on individual physiology and exercise regimes. 1. Take short rides on level or gently sloping terrain for a few days before attempting long distances or more aggressive riding. 2. Downshift and maintain a high RPM when climbing hills. Failure to do so can lead to possible knee irritation or injury. 3. If you feel tight or sore in some areas, you will benefit from a warm up and stretching routine before and after riding. Fitting Your Sun Recumbent. Your Sun Recumbent will accommodate most body sizes. In order to ride comfortably and safely, you should adjust the Sun Recumbent to fit your body. There are 3 adjustments that can be made to customize the fit of your Sun Recumbent: a. Seat distance from the pedals b. Seat back angle c. Handlebar height and angle 1. When seated, your knee should be just slightly bent when the forward foot is in the farthest posi- tion. This is adjusted by moving the seat along the length of the frame, moving you closer or farther away from the pedals (see Seat Installation, Removal and Adjustment on page-10). For full power, leg extension and the least stress on your knees, double check your seat to pedal position in the following way: Try to touch the heel of your shoe to the pedal with your knee locked. You should barely be able to reach the flat part of the pedal. Now when you put the ball of your foot on the pedal. You should have the proper bend in your knees. (Fig. 3.1) (Fig. 3.1) 2. The handlebars should be at a height that is most comfortable for your hands and arms and that allows knee clearance when pedaling. The handlebars are adjusted by raising or lowering the stem and adjusting the angle. (see Handlebar Adjustment and Alignment page-10).

Loosen the 2 stem bolts with a 6mm hex wrench and position the stem down parallel to the handlebar. Tighten the top stem bolt completely, then tighten the lower bolt securely (Fig. 4.1) 2. Apply a light coat of grease to the expander wedge. 3. Place the bottom end of the stem into the fork. Be sure that the minimum insertion line is not exposed. Tighten the expander bolt with a 6mm hex wrench. 4. Remove the spacer from the front fork. 5. Open the front wheel quick-release lever. Loosen the QR nut a few turns. 6. Seat the wheel axle in the slot on the front fork dropouts. Make sure it is fully seated in the slot. Traditionally the QR lever is on the left hand side from the seated position. (Fig. 4.2) 7. Make sure the front wheel is centered property between the fork blades. (Fig. 4.2) Page 5 Handlebar and Front Wheel Installation (continued) 8. Tighten the nut and close the quick-release lever with firm pressure (see Quick Release Lever Operations on page 16, for full operation instructions). 9. Align the handlebars perpendicular to the front wheel by standing with the front wheel between your legs. Look at the alignment of the handlebars in relation to the front wheel.
